How to download and install macOS
- 10.15 macOS Catalina

Many of these MacOS installers arrive as InstallAssistant.pkg files that will extract the full installer into the /Applications folder on the Mac.
New versions of MacOS installers are typically available through the Mac App Store, accessed through a computer that is compatible with the latest Mac system software release.
Older versions of Mac OS X installers can often be downloaded as well, but from different sources.
For earlier versions of Mac OS X, including Mac OS X Mavericks 10.9, Mac OS X Mountain Lion 10.8, Mac OS X Lion 10.7, Mac OS X Snow Leopard 10.6, Mac OS X Leopard 10.5, Mac OS X Tiger 10.4, and before, the process to obtain those installers differs a bit.
Mac users can download the latest macOS installer available from the Terminal by using the following command string:
softwareupdate --fetch-full-installer
You can also download specific installer versions by using the following syntax, replacing the asterisks with version number:
softwareupdate --fetch-full-installer --full-installer-version **.**.*
For example, to get macOS 11.3.1 the syntax would be as follows:
softwareupdate --fetch-full-installer --full-installer-version 11.3.1
If you had at one point in time purchased or downloaded a version of MacOS or Mac OS X from the Mac App Store, then you should be able to re-download it from the Mac App Store by going go the “Purchases” section. This can typically be used to access downloads for installers for MacOS 10.14 Mojave, 10.13 High Sierra, 10.12 Sierra, 10.9 Mavericks, and 10.8 Mountain Lion, though there are some caveats and exceptions.
- Open the App Store
- Go to the “Purchases” section (newer App Store versions must go to Account > Purchases)
- Scroll down the list of Purchased items to locate the Mac OS X Installer version you wish to re-download, then click on the download button
This works particularly well if the Mac you’re downloading the software onto is running an older version of Mac OS X.
This approach for re-downloading older OS X installers from App Store Purchases section works for obtaining many older versions of Mac OS X, particularly if the machine doing the downloading is running an older Mac release too. For example, re-downloading Mavericks from Yosemite, whereas if you’re running the App Store from newer versions of MacOS you’d need to follow the links further above to download the installers directly, or via the App Store links.
If you’re a registered Apple developer then you may be able to download Mac OS X Snow Leopard and Mac OS X Leopard directly from Apple ADC using the following links:
- Download Mac OS X Snow Leopard (DMG file, via Apple ADC downloads)
- Download Mac OS Leopard (DMG file, ADC download link)
Apple also sells some older Mac OS X versions (10.8, 10.7, 10.6) for convenience:
- Buy Mountain Lion from Apple for $20 10.8
- Buy Lion from Apple for $20 10.7
- Buy Snow Leopard from Apple 10.6
If you have a Mac computer and have connected an Apple ID to the Apple Store, then you may be able to download that OS version for free in the future even if it was one of the Paid versions. Unsure if you first have to "purchase" it in the store to add it to your library (purchased app history for free) and have future rights to download it again using the App store.
Rescue disc, bootable recovery drive for Macs
- Format a 16GB (or larger) thubdrive as Mac OS Extended
- Download a MacOS installer (usually from the Apple App Store)
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Drivereplace
Install macOS Big Sur.appwith your downloaded installer package. replace/Volumes/Drivewith your USB thumbdrive mount path.
Macs with Apple Silicon (M1, M2, M3, etc) do not support Boot Camp (only Windows virtualization).
